+

+

Each B.A.T.M.A.N (better approach to mobile ad-hoc networking) node stores routing information about the neighbouring node it can reach. If because of packet loss etc. another node cannot be reached it will not be part of the local node's routing information.

+

+

B.A.T.M.A.N Advanced is the next generation implementation that works on the Ethernet layer instead of the IP layer. That way the mesh-net can be seen as an ethernet switch allowing easier node to node setups and providing services ''inside'' the mesh-net.

Mesh networking allows communication with others without the need for network
infrastructure such as cellular base stations or wireless access points.
A mesh network treats everyone's computer as a wireless router and learns about
the links in the network, computes paths between all users, and updates the IP
routing tables so that you can send packets to anyone else who is part
of the mobile ad-hoc network (MANet).

The minimal requirement to run Mesh networking is having at least one network interface configured.
A WLAN or Bluetooth network interface can be used for this (actually you could use a wired
interface but you won't be very mobile then!).

Introduction

Mesh networking allows communication with others without the need for network
infrastructure such as cellular base stations or wireless access points.
A mesh network treats everyone's computer as a wireless router and learns about
the links in the network, computes paths between all users, and updates the IP
routing tables so that you can send packets to anyone else who is part
of the mobile ad-hoc network (MANet).

Hardware

The minimal requirement to run Mesh networking is having at least one network interface configured.
A WLAN or Bluetooth network interface can be used for this (actually you could use a wired
interface but you won't be very mobile then!).

Software

There is different software out there supporting Mesh networking.

Netsukuku

Netsukuku is a mesh network or a p2p net system that generates and sustains
itself autonomously. It is designed to handle an unlimited number of nodes
with minimal CPU and memory resources.

Mobile Mesh

Mobile Mesh has been developed for mobile
ad-hoc routing protocols. Mobile Mesh is developed part of a research project at The MITRE Corporation.

LUNAR

LUNAR stands for Lightweight Underlay Network Ad-hoc Routing
and implements a bare-bones on-demand route discovery protocol with broadcast dampening and reconfigures
communications paths typically within 3 seconds. LUNAR includes automatic IP gatewaying and supports
IP unicast and broadcast. A dedicated LUNAR over Bluetooth version is available running over a Bluetooth network using BlueZ.
